Parkinson's disease (PD) is a neurodegenerative disorder of unknown aetiology with an estimated incidence of 4.5-16/100,000 persons/year.

BIA 9-1067 is currently being developed by BIAL (Portela & Cª,S.A.) to be used in addition to L-DOPA (Levodopa) /carbidopa or L-DOPA (Levodopa) / preparations in PD patients. Promising results have been obtained for BIA 9-1067 in previous studies.

Official Title: Efficacy and Safety of BIA 9-1067 in Idiopathic Parkinson's Disease Patients With "Wearing-off" Phenomenon Treated With Levodopa Plus a Dopa Decarboxylase Inhibitor (DDCI): a Double-blind, Randomised, Placebo-controlled, Parallel-group, Multicentre Clinical Study.

Primary Outcome Measures:
  • Efficacy of 2 BIA 9-1067 (25 mg, and 50 mg) Compared With Placebo, When Administered With the Existing Treatment of L-DOPA Plus a DDCI (DOPA Decarboxylase Inhibitor) [ Time Frame: 14-15 weeks ]
    Efficacy of 2 BIA 9-1067 (25 mg, and 50 mg) compared with placebo, when administered with the existing treatment of L-DOPA plus a DDCI (DOPA decarboxylase inhibitor), in patients with PD and end-of-dose motor fluctuations. The primary efficacy variable will be the change from baseline in absolute OFF-time at the end of the DB period.

Secondary Outcome Measures:
  • UPDRS (Unified Parkinson's Disease Rating Scale) Sections I (ON), II (ON and OFF), and III (ON) [ Time Frame: 14-15 weeks ]

    Total UPDRS SCORE (I, II (ON), and III) Change from Baseline to Endpoint

    • UPDRS I evaluation of mentation, behavior, and mood
    • UPDRS II self-evaluation of the activities of daily life (ADLs) including speech, swallowing, handwriting, dressing, hygiene, falling, salivating, turning in bed, walking, and cutting food
    • UPDRS III clinician-scored monitored motor evaluation The UPDRS I, II and III scores and subscores are calculated as the sum of all individual items. If one or two items in a scale are missing, they will be imputed with the mean of the non-missing items of that scale.

    Subscale has 0-4 ratings, where 0 = normal, 1 = slight, 2 = mild, 3 = moderate, and 4 = severe

    The final cumulative score will range from 0 (no disability) to 199 (total disability).

  • Parkinson's Disease Sleep Scale (PDSS) [ Time Frame: 14-15 weeks ]

    The Parkinson's disease Sleep Scale (PDSS) is a specific scale for the assessment of sleep disturbances in subjects with PD. The PDSS score is calculated as the sum of all single items. If one or two items are missing, they will be imputed with the mean of the non-missing items. If three or more items are missing, no imputation will be done and the score will be set to missing.

    Subscale has 0-10 ratings, where 0 = severe and 10 = normal

    The PDSS total score is a sum score of all 15 questions and ranges from 0 to 150, with lower scores meaning more disability.

  • Non-motor Symptoms Scale (NMSS) [ Time Frame: 14-15 weeks ]

    The Non-motor Symptoms Scale (NMSS) consists of 30 questions, covering 9 dimensions, whereby each item is scored for severity and frequency: Severity None 0 Mild (symptoms present but causes little distress) 1 Moderate (some distress or disturbance to subject) 2 Severe (major source of distress or disturbance to subject) 3

    Frequency Rarely (<1/wk) 1 Often (1/wk) 2 Frequent (several times per week) 3 Very Frequent (daily or all the time) 4

    The product of frequency and severity is calculated for each item and each dimension score is defined as the sum of the frequency*severity of the respective items. If frequency or severity of a single item is missing, the domain score will not be calculated. The NMSS total score is defined as the sum of all domain scores.

    The NMSS total score is calculated by adding all domain scores (0-360), and lower scores mean less disability.
